It sent my Win7 system into BSOD - for the first time (this OS seems to be a very stable one). It also gave itself permissions in the Windows properties permissions section to call home and take over all control. It was a devil to remove. Beware.

Best practices for resolving atitray issues

A clean and tidy computer is the key requirement for avoiding problems with atitray. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
